Title: Improvements in and relating to means for tuning radio sets
IPC: H03J5/12
Filed: 1928-06-09
Abstract: 319,037. Marvin, H. N. June 9, 1928. Receiving-sets, construction of. - A wireless receiving-set has a tuning-element 12, 13 operated by a plurality of independent members 2 - - 6 each representing a wave length and the operation of a member moves the tuning-element to a position appropriate to the corresponding wave length. To tune to a desired station, an appropriate push-button 26 is operated and is locked in position by a spring-pressed plate 56 until released by the actuation of another push-button. The push-button slides a cylinder 6 over a screw-threaded rod 34 until it encounters a nut 35, which is adjusted on the rod according to the wave-length appropriate to the push-button. Link-members 42, 43 are attached to the rod 34 and rotate freely about a shaft 27, when the rod is actuated, until they encounter a stop 45 on an arm 44 rigidly fixed to the shaft. The consequent rotation of the shaft rotates the tuning- condenser 12 to the desired position through gearing 28, 29. Similarly the condenser 13 is rotated through an adjustable nut 39 on the rod abutting against a sliding-sleeve 38 to which are attached link members 33, 37 fixed to a shaft 30. The condensers are spring-biased towards the zero position by chains 51, 53 connected to members 50, 52 fastened to sleeves 46b, 46a round which are coiled springs 47 having one end anchored to a pin 48 and the other to a member 49 fastened to the sleeve. To enable condenser dials 9, 10 to be operated in the normal manner the spring-bias is removed by a push-rod 7 on which rotates a link member 58 having a pin 59 which engages the members 49. A pushbutton 64 actuates an on-and-off switch 60, 61.

Title: Improvements in or relating to the manufacture of aldehydes or alcohols
IPC: C07C29/16
Filed: 1951-07-17
Abstract: Aldehydes and alcohols are made by an oxo synthesis wherein a cobalt hydrocarbonyl catalyst is prepared in the gaseous state in a continuous manner by bubbling a mixture of CO and H2 at about 100-200 DEG C. and 50-250 Kgs/cm2, through a suspension of finely powdered and dehydrated cobalt oxide or metallic cobalt in a heavy hydrocarbon of the "gas oil" class preferably in the presence of about 10-50 per cent., with respect to the cobalt compound, of a cobalt salt of a carboxylic acid, introducing the resulting gaseous mixture into the olefine to be treated, heating in continuous circulation at the above temperatures and pressures and separating the cobalt from the product.  Cobalt salts of carboxylic acids specified are stearate, heptanoate and naphthenate.  Cobalt in the products may be precipitated as the metal by means of a current of hydrogen at about 100 DEG C. and mechanically or magnetically separated.  During precipitation of the cobalt with hydrogen if temperatures of about 180-200 DEG C. are used the aldehydes will be converted to alcohols. Metallic cobalt or cobalt oxide should be added to the suspension periodically and recovered cobalt may be recycled possibly after oxidation. Desulphurized water gas may be used in the supply of CO and H2.  Advantageously the water gas bubbling through the suspension is equal to that taking part in the oxo synthesis.  An illustration is provided of a suitable layout of apparatus and in examples water gas is (1) passed through a heavy hydrocarbon suspension of cobalt oxide and stearate at 140 DEG C. and 150 Kgs./cm2 and reacted with C5 olefines at the same temperature and pressure and the aldehyde product decobalted and partially converted to alcohols by treatment with hydrogen at 120 DEG C. and 20 Kgs./cm2; (2) passed through a suspension in C8-C10 hydrocarbons of cobalt oxide and cobalt salts of C8 fatty acids at 140 DEG C. and 150 Kgs./cm2 it being shown that cobalt is removed therefrom as cobalt hydrocarbonyl at a substantially constant rate, and in (3) passed through a suspension in a hydrogenated gas oil of cobalt oxide and cobalt salts of C8 "oxo" fatty acids, cobalt oxide being added at intervals, at 105 DEG C. and 150 Kgs./Cm2 and reacted with C6 Fischer-Tropsch olefines at 130 DEG C. and 150 Kgs./cm2 the aldehydic product being decobalted and hydrogenated at 180 DEG C. and 20 Kgs./cm2 by treatment with hydrogen.  Specification 644,655 [Group XXVIII], is referred to.

Title: Improvements in or relating to solid moderator arrangements for nuclear reactors
Inventor: BROUARD DANIEL
IPC: G21C5/04
Filed: 1961-05-11
Abstract: 933,982. Moderator structures. COMMISSARIAT A L'ENERGIE ATOMIQUE. May 11, 1961 [May 25, 1960], No. 17246/61. Class 39 (4). A solid moderator structure, e.g. of graphite, comprising adjacent parallel vertical columns of square cross-section with vertical axial channels has two coaxial groups of columns, the columns of one group being of different crosssectional area to those of the other group, each column being formed by a number of rods separated by briquettes of the same cross-section and having channels coaxial with those of the rods, the briquettes forming horizontal layers, and connection means being provided between the columns of the groups, and between the two groups, at the level of each layer of briquettes. In the embodiment described, there is a central group 1 of 256 (16 x 16) columns surrounded by a peripheral group 2 of 60 columns, 16 columns of group 1 being equal in length to 14 columns of group 2. The number of vertical channels per unit volume is thus greater at the centre of the reactor core than at the periphery in order that the neutron flux may be more uniformly distributed. The columns in both groups are spaced from each other to allow for Wigner growth. Connection between the columns of group 1 is made in a similar way to that between the columns of group 2, as shown in Fig. 2, rods 5 forming the columns being separated by briquettes 8 to which they are connected by mortice-and-tenon joints. The briquettes 8 are provided with grooves, one in each lateral face and one in each of a pair of opposed comers, so that they may be connected to adjacent briquettes by keys of length slightly less than that of the grooves in which they fit with clearances between their lateral faces and the grooves. As shown in Fig. 1, briquette 8 is connected to briquettes 10, 11 by keys 12, to briquettes 13, 14 by keys 15, and to briquettes 16, 17 by keys 18. Clearances are provided between the ends of the keys and the bottoms of the grooves to allow for Wigner growth. The connection between the two groups is effected by 24 keys, briquette 23 being connected to briquettes 3, 24 and 25 by keys 26. 28 at each corner of group 1 and briquettes 19, 20 to briquettes 21, 22 by keys 26, 27 mid-way between each corner. In this embodiment, the rods and briquettes are of graphite but any other suitable material, e.g. beryllium or beryllia may be used. Specification 897,534 is referred to.

Patent GB-757148-A (GB)
Title: Process for the production of alcohols and esters
Filed: 1954-06-15
Abstract: A process for producing alcohols or esters comprises heating a mercaptan with an "oxygen compound of a heavy metal" by which term is meant the oxides, hydroxides and organic acid salts of the heavy metals and also compounds of the heavy metals which yield the oxides under reaction conditions, for example the carbonates. Preferred organic acid salts are those of carboxylic acids containing 1 to 8 carbon atoms and those of acids no stronger than formic acid.  They should be finely divided, for example in the fluidized state.  If salts of heavy metals are used esters of the corresponding acids usually are obtained, or in some cases are decomposed to the alcohol during the reaction.  The process is applicable to alpha mercaptans obtained from the alpha alkenes produced in hydrocarbon cracking, and the products can be esterified, for example with sulphuric acid, to give alpha esters. An inert diluent, for example cetane, may be present in the reaction mixture.  In Examples (1) to (3) primary cetyl mercaptan heated with lead oxide (PbO) at 270 DEG  C. or lead acetate, and primary tetradecyl mercaptan heated with lead oxide yield the corresponding primary alcohols; (4) primary tetradecyl mercaptan is heated at 220 DEG  C. with lead acetate and the product is extracted with isopropyl ether and pentene, the extract being treated with chlorosulphonic acid to sulphate any alcohol present. The residue, not affected by chlorosulphonic acid, is an ester which can be saponified with potassium hydroxide solution.
